AEROPLANE.

E orescaples.

' are frames hingedly Another very important object of the invention resides in the provision of an eleva- '-.tor and a rudder formed with air spaces and air outlets at the exit thereof, so as to attain themaximum efliciency and maneuvering 1n the air.

"Another very important object of the 1n- 'vention resides in the provision of control means of the nature just mentioned which mountedto normally return to and stay in a predetermined position for horizontal flight so as to relieve the aviator of considerable strain during a long flight when the plane is maintaining a straight ahead horizontal flight.

- Another very important feature of the invention residesin the provision ofa landdrag-stick so mounted and constructed that 'it may functionjas a rudder in the A still furtherfimportant object. of the invention resides in the-.provision of an aeroplane of this nature'which is simple in its construction, compact and convenient in its arrangement of parts, stron and durable, thoroughly efiicient and relia 1e in use and operatlon, and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in view, as .will appear as the description proceeds, the invention resides in 'certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more Fully described and claimed. In the drawings:

Figure 9 is a detail horizontal section taken substantially on "the line 99 of- Figure 4.

Referring-to the drawings in'detail, it will be seen that the numeral 5 denotes a hollow fuselage, constructed of sheet metal owing the 'means for 0- or any other suitable material and formed so as to taper 'forwardl Sand rearwardly from the central portion t ereof. -Each'side of the front tapered portion of .the fuselage 5 is formed with elongated'air pockets 6 inclining upwardly and forwardly and having the edges thereof corrugated to. form outlets or air escapes. A -su1table' propeller 8 is mounted at the nose of the fuselage and will be driven by suitable prime movers in the fuselage -(not shown)l A pontoon 9 is mounted on the bottom of the central por-" tion of the fuselage 5 and is hollow having its side walls converging downwardly toward each other to-meet m an apex edge.

.A landing ear 10-is mounted on the,fuse-- lage, below t e pontoon 9. The bottom" of the rear taperedvportion of-the fusela 65 is formed with an elongated longitulfinal air pocket 11. Theedges of the pocket. 11 are corrugated as at 12 to formair outlets or escapes.

A superstructure 14 is mounted above the central and forward portions of the fuselage 5 and includes a package compartment 15, an aviators compartment 16, and a front compartment 17. A casing of triangular formation 18 is hingedly mounted as at 19 to the rear of the superstructure, so that it. may be swun to one side as indicated to advantage in igure 7, for the loading and unloading of baggage. Hinged aperturedcars 20 are mountrl on the rear edge of the casing 18. Below the top of the fuselage 5 there is mounted a bearing'22, by means of arms 23, and in this bearing is a rotatable shaft 24, having a sprocket in the upper end thereof. A pin 25 is insertable in the socket thereover for controlling the rudder.

to extend above the fuselage through the Obviously the pin may be removed to remove the rudder so that the casing 18 may be swung to one side for loading or unloading the baggage. Platforms 32 extend along the sides of the superstructure 14 and have railings 33 rising from the outer edges thereof. The rudder 27 is concaved mwardl y on both sides to form air pockets 34'and the edges are corrugated as at 35, to provide-air outlets or escapes. This rudder is provided with straight upper and rear. edges-at right angles to each other and a top edge which is curved downwardly from the rear edge to the hinged end.

' An elevator 37 is spring hingedly mounted as at 38 on the rear end of the fuselage 5' and the rear 'edges of fins 39 projecting laterally from the rear end of the fuselage. The elevator 37 is'provided with a concaved lower surface forming an air pocket 40 and a corrugated edge 41 forming the air escape or outlet. The fins are concaved on their bot tom surfaces as indicated at 4:1 and the edges are corrugated as at 42 to provide'air es-. capes or outlets. The rudder 4.0 is operated by means of a pin or shaft 45, and a sprocket and chain mechanism 46.

A combined landing drag stick and rudder 47 has its upper end journaled in abearing 48, at .the rear of the fuselage to depend downwardly therefrom and incline slightly rearwardly and the bottom end curves rear-'- wardly as at 49. A brake structure 50 inclining downwardly and rearwardly from the rear portion of the fueslage has a collar tion as a rudder, for guiding the floating airship on the water.

51 in which the lower portion of the member 47 is rockable. A, chain and sprocket mechanism 52 is provided, for rotating this member 47 when in the water, so as to func- Bird like wings 57 project one from each side of the central portion of the fuselage. Each wing has a-strai'ght rear edge at right angles to the median longitudinal dimension of thevareoplane and a curved front edge converging gradually toward the outer end of the straight edge terminates in a point therewith. These wings are of hollow construction, including upper seats 58 and lower seats 59. These seats are somewhat-concentrically curved but meetat their rear and forward edgesso as to be air tight. The forward edge of each wing is formed by having the seats 58 and 59 abruptly converge toward each other and terminate in abutments as is 'scription.

indicatedat 60 so as to provide an air non-- I resisting edge. 'These lower seats 49 are prov'ided with air pockets, and the rear and inner edges thereof are corrugated as at 61 to bination with the air pockets of the fuselage, it will be-seen that this aeroplane is possessed of considerable soaring capacity without the aid of the propeller, so that if the aeroplane is travelling at a sufficient height and motor trouble occurs, it is probable 'that repairs could be made before an emergency landing. I

Rising from the superstrlu-ture 14 are two' poles 63, which ma be used to mount an 2111- tenna 64 for a ra io receiving and sending set, and in an emergency these poles may be used as a sail when the plane has made an emergency landing in the water, so that with the aid ,of such a sail and the rudder afforded 'practiceit will attain .the features of advantage enumerated as desirable in the statement of the nvention and the above de- It .will be apparent that changes in the details of construction and in the combination and arrangement of parts may be resorted to, without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.
